Custom Polk RTA 12B's. These are Polk 12 cabinets with 12B crossovers.
Crossovers rebuilt with Erse capacitors. The top crossover was split into two and put in the bottom of the cabinet.
6600X drivers, all have JB Weld on the magnets, and there is one extra driver
I have two pair of tweeters, one set is Denmark. They are currently mismatched but can be matched.
Passive radiator is from SDS Speakers
All drivers are mounted with T-Nuts.
Custom cherry tweeter mounts.
Cherry veneer on the cabinets. Custom bases are not attached but could be.
There is a thread here on my rebuild process.

Asking $500. These are way too heavy to ship. I live in Metro Denver and can meet if its a reasonable distance.

NOTE: There is some splitting of the veneer on the sides of the cabs. This does not impact the sound. It's only the veneer. Colorado was not kind to it...Carver C-1, M-500 MKII, Yamaha HTR-5835, Polk RTA 12BM's (M-for mod'd).
